pulse jet's & turbo jets

[bigfootrules31]

after watching many a videos on youtube about pulse jets, i want to try making one.

has anyone else made one before, and know some tips

if i can make one, i want to try ues it on a bike or somehting.

ive also seen jets made out of a turbo, so i might try find an old one to try make a turbo jet aswell. the only thing thats stumpoping me with that design is the oiling system, as i want them to move something will i need to make it batter powered or somethine

i got over the idea of making a pulse jet real qwik. the idea of the reed valves being so sensitive really worries me, beacause im not a real precision kind of guy...
i think a p-jet would be cheaper to make, but i like turbo jets much better...

besides you would need a HUGE pulse jet to push you and the kart. HUGE!!!

matter of fact, one of the guys on this forum(lemegacool made a great log about his own turbo jet. heres the link:

i think a turbo would be much easier to make and it would be cooler too... as in more awesome... but, it is more expensive, no doubt... especially if you get into all the guages and electronics for monitoring it.

making the pump battery powered would be good, and its really easy too. or you could... yeah thats teh only way i can think of.

lemegacool's is a little on the large side, but thats ok, it just costs more.
make sure to check the tail end of the thread where lemegacool answered some of the questions i had, i think you will find that helpful, he even recomends some free software to help design the turbo jet.

good luck!

A turbocharger from a car or truck can be used to make a turbojet engine, however there's a packaging problem and if you look at all the videos you end up with a large rectangular "cage" with all sorts of stuff in it, with the turbojet's outlet at the top rear.

This is not necessarily bad, but it makes it more difficult to stick on a small vehicle like a bike or a kart. Maybe it's possible to relocate some of the parts around the chassis of the kart for better weight distribution as well as better placement?

The best arrangement is an inline arrangement, and that's easier to achieve with a homemade pulsejet.

Much easier I think than all the stuff necessary to make a turbocharger-based thrust system.

ok, i found 2 different plans, 1 for a chinese valvless pulse jet and the other for a different jet.
they both are supposed to giv about 25 punds of thrust....luckyly i have engineering today so im going to try make a smaller model for some testing

 

[bigfootrules31]

i started to build one, a chineese pulse jet. i followed a set of plans except for one of the chambers is square. it fires and gives a bit of a humm, but i cant get it to run

how about something like this http://www.aardvark.co.nz/pjet/gokart.htm

 

[lemegacool]

yeah i did one ... msg me if you want advice...

atm im looking for a turbo, do you still have yours

how much thrust did she make

yes i do still have it... i could'nt get it to self sustain yet... lack of fuel... i'm currently developping a diesel fueling system to get the ***** spooling ! lol according to jestspecdesigner it should produce 60+lbs of thrust... with an insane whine LOL

sweet. ill keep my eye out for one, i need less projects and more money
